Working on a 2009 LMM, 100% stock. I am getting real high , (possibly erroneous?) readings for one of the egr temp sensors. Anyone experienced this before? Any ideas? Truck has cel and is throwing codes p0101 p0102 and p0113 which all have to do with the MAF. Al wiring is good to maf and I already tried sapping maf with another known good one and no change. Truck shows on doc “engine power reduced”.

Have you tried doing a manual regen on it yet? I think you mean egt, not egr sensor. The p0101 and p0102 can both be set from a plugged dpf or also a crack in the intake tube, but with the high egt's, I would be leaning more towards a plugged dpf in needof manual regen.
